At each iteration, SSU sequences were merged into one sequence if the identity of non-gapped positions in a global alignment was greater than 97%. A single SSU sequence (and its prior probability) was divided into two sequences if the second most probable base in more than 4% of all positions had a probability greater than 10%. In this way, sequences that evolved over iterations to be the same were merged, and sequences with evidence from the reads for multiple OTUs were duplicated and allowed to evolve as separate OTUs in future iterations.

“The relative abundance of each MAG was estimated using the fraction of reads in each sample mapping to the respective MAG. Normalized on the size of that bin, this yielded the measure fraction of reads per nucleotide in bin. This measure was chosen since it is comparable across samples with varying sequencing output and different bin sizes. Using the CONCOCT input table, multiplying the average coverage per nucleotide with the length of the contig in question and summing over all contigs within a bin and within a sample gave the number of reads per bin within a sample. The fraction of reads in each sample mapping to each bin was then calculated by dividing this value with the total number of reads from each sample, after having removed duplicated reads.”

# print(p_mag8_deseq_KO_gsea)In order to check unspecific mapping sample reads were mapped consecutively to every bin using BBmap.sh. This approach allows us to check the mapping specificity by evaluating the distribution of read identity to the putative genome bin.
Competitive mapping was performed through blastn searches against a 1M and 10M read subsample from the interleaved fasta generated after QC (seqtk). Shell script used to achieve this:
#!/bin/bash
set -e
for file in `cat map.list`

echo $file
